The Bonus Guarantee ensures that freebie payouts achieve a specific limit.The Heidi scatters activate up to 100 free spins.Jackpots, wilds, and bonus guarantees are other features to expect in the pokie. Heidi, the voluptuous barmaid, sits atop the reels with a smile plastered on her face and also appears on the grid as the scatter, awarding up to 100 free spins. Each column serves a traditional lager from a beer tap, and punters enjoy the cold brew for stakes between 0.75 and 40 credits. The atmosphere of the country’s drinking houses is captured on a 6x5 grid with forty bet lines. The pokie machine embodies the relaxation after drinking a cold beer to combat the hot summer sun, and few cultures do it better than the Germans. Heidi’s Bier Haus slot game by Williams Interactive is a follow-up of Bier Haus released by the same developer in 2015. Visit a German bar and have several glasses of beer on a 6x5 playtable, and walk away with one of four jackpots, up to 100 free spins, and a bonus guarantee feature.
